Article Synopsis
  • A new electrophysiologic mapping technique helps identify the central sulcus and abnormal cortical regions in patients with tumors or epilepsy.
  • Electrocorticographic recordings from 25 patients showed that low coherence was found across the central sulcus, confirming its location in 11 out of 12 cases analyzed.
  • The technique also identified tumor locations in the sensory-motor region effectively and noted high coherence areas in epilepsy patients, though these did not correlate with mesial temporal lobe tumors or inter-ictal spiking.

Human electrocorticographic findings recorded from subdural arrays of electrodes were topographically mapped directly onto magnetic resonance images of gyral anatomy. With this technique gyri involved in generating somatosensory evoked potentials and epileptic phenomena are easily identified. Regions of the cortex which exhibit local spectral changes associated with cognitive tasks can also be visualized.
